DT Connector Crimping Tool | Size 16 Closed Barrel Ratchet Crimper | Deutsch DT Compatible | 14-20 AWG

Crimp DT-style connector contacts the right way. This closed barrel ratchet crimper is specifically designed for Size 16 solid and rolled contacts used in Deutsch DT-style connectors — the standard in automotive, marine, agricultural, and motorsport wiring harnesses. If you're building or repairing a DT connector loom, this is the tool you need.

DT contacts cannot be crimped correctly with a standard insulated terminal crimper. They require a 4-way indent closed barrel crimper that engages all four sides of the contact barrel simultaneously, producing a gas-tight crimp with maximum conductivity and pull-out resistance. This tool delivers that — with a ratchet mechanism that locks until the full crimp cycle is complete, so every contact is correctly formed before the tool releases.

Key Features

• 4-way indent closed barrel crimping — correct crimp geometry for Size 16 solid and rolled DT contacts
• Ratchet mechanism — won't release until crimp cycle completes, eliminates under-crimped contacts
• Suits 14–20 AWG wire — covers the full wire gauge range used with DT-style connectors
• Compatible with Size 16 stamped and solid contacts — works with DT-style, Deutsch DT-compatible, and equivalent connector contacts
• Drop-forged alloy steel jaws — hardened for workshop durability and long service life
• Ergonomic non-slip handles — comfortable for high-volume harness work

Compatible Contacts

• Deutsch DT-compatible Size 16 stamped contacts (14–18 AWG)
• Deutsch DT-compatible Size 16 solid contacts (14–20 AWG)
• All DT-style connector contacts including 2, 3, 4, 6, 8, and 12-pin housings

Why You Need a Dedicated DT Crimper

DT connector contacts use a closed barrel design — the contact barrel is fully enclosed, not open like a standard insulated terminal. A standard automotive crimper will crush rather than indent the barrel, producing a poor mechanical and electrical connection. The 4-way indent action on this tool engages all four sides of the barrel simultaneously, forming a gas-tight crimp that meets automotive wiring harness standards.

Ideal Applications

• Building and repairing Deutsch DT-style wiring harnesses
• Automotive OEM and aftermarket harness work
• 4WD, off-road, and motorsport wiring builds
• Agricultural and heavy machinery loom repair
• Marine and boat wiring harnesses
• Truck, bus, and commercial vehicle electrical work
• Auto electrician van stock — pairs with DT-style connectors
